docs: R5-V1 landed — wiring handoff, register TS-35 correction, #167, roadmap

Housekeeping around the R5-V1 core port (3d89446d):
- r5-wiring-handoff.md: the V2/V3/V4 GameWindow-wiring plan (per-entity
  IPhysicsObjHost, AP-79→voyeur behavioral-equivalence anchor, TS-39 sticky
  integration, mt-0 flags, #164, facade). These are the visual-gated slices.
- ISSUES #167: ConstraintManager leash unported — arming (SmartBox) + two
  x87 distance constants BN elided; deferred (needs cdb/Ghidra). TS-35 stays.
- Register TS-35 corrected: R5 recon proved the "write side" is the
  ConstraintManager server-position rubber-band leash, NOT the earlier
  "per-cell contact-plane / doorway-jamming" guess. Oracle addresses fixed.
- Roadmap Phase R: R5-V1 shipped, R2-R4 visual pass PASSED, next = wiring.
